- Be it nowii that .I, FRANK W. WALQUIST,

a citizen ofthe United States, residing in the State of -New York, have invented certain I Tubes,"of' which the followin is a specification, reference being had to t e accompanya ing drawings, forming a part hereof.

' rious ways.

Tubes. for coolers, condensers, and for .many other uses are commonly-made, for

economy and strength, of steel 'or iron. It is highly-desirable in many cases,- however,

that such tubes of steel -or iron. should be lined with copper or tin or some metal whichis less affected by the gas or liquid which passes through the tubes. Ir such "tubes were perfectly true, the lining thereof with tin or copper The fact is, however, that such tubes are not and cannotbe made perfectly 1 true without great expense. 7

- It is according y the ohject of this invenjti on to make it possible to line tubes of iron more or less internally from a tru y cylin-.'

or steel or other metal which ma depart I dfical form with other metal, such as coPPer 'ortinm l H 3 such external-diameter as to 'be. capable of I selected, and the-'lining tube is then "expandintimate 'contactwith'thecaused to traverse scale of; the "e ed into close and end toend.

the expaiider and the tubes obviously may character of the tubes to be-lined andupon whether it is more convenient to rotate or-to -,the other, his mounted soas to turn with the shaft 0 and't'o move longitudinall thereon, being-preferably splined'on' the s aft, asat'; t. The adjacent .endsof the two sleevesh retain the rollers in place'when not-in .operation, a cage maybe prov ded comprising two inembers Z and Z, secured together by bolts I, such ca e tgeing mounted loosely upon the members and i. The end oi the shaft 0,

which is preferably reduced, as shown, to

I form a shoulder c for cooperation with thesleeve member h of theexpander, is threaded at itsend c to receive the nut m, which acts,, through awasher m and a spring 12., upon the longitudinally movable member tor the exac pander. t

L In operation the tube e'to. be lined having been secured in the carriage g, the ex ander is introduced within the render the en e and its lining, and the nut m is set up until,

is through the spring. n and the action of the tapered ends h? and t the rollers and 7c" are forced outwardly against the "ning-tube with the degree of pressure necessary to expand it'into intimate contact with the tube to e; Two opposite rollers 70 k as shown in Fig.'

9 will suffice in some cases but it is generall desirable to provide a larger number of roll: ers in order that the lining-tube 6 may be supported at many points, about its internal -2 5 circumference, and the expansion thereof into intimate contact with the tube e be 1 made thereby themore certain. If two rollera are only employed, as shown in Fig. 9, they are preferablyofe ualdiameter. They may 3c also be of equal diameter when three rollers are employed, as shownin Fig. 14. If four or more rollers are employed, as indicated in Figs. 4, 6, 10- 11, 12, 13,- and 15, one or more of 'therollers, as 1:, have the maximum 3 5 diameter, while the remaining'rollers of the set as k, are' of smaller diameter. ,The rollersjc ofthe maximum'diameter act more particularly as expanders to force the lining-- .tube into inequalities the other tube, as 40 indicated at the top ofFig. 6, while the other lining-tube outwardly and to prevent. a mere bend in the metal from following the expandin other respects r mains asbefore,.excepti that the cage Z may be, modified in form to.

' cooper-a e with the balls. The inclined or tapered ends h. and if ofthe sleeve members Ib and tcooperatedirectly with the balls to rerce them outwardly.

It. will now be understoodthat when the tube and its lining have beenassembled sand secured'in the clamps and the expander introduced at one end,"the required pressure 'beingfsecuredaby' setting up the nut m, the shaft- 0 is made to rotate rapidly, and at the end to the other. tion is -to expand the lining-tube into intitubes is thus conducted with great 'ra idity,

other. rollers," as k, act moreas carriers to hold the -.press one of said sleeves yieldingly toward the "other, means to rotate, one 0 same time the tubes are fed forward to cause the expander to traverse the device from one Theeflect of this operamate contact with the outer tube at all points regardless of such inequalities in the inner surface of the outer tube as may have resulted fromthe process of manufacture of the outer tube. The operation of lining and the union between the outer tu e and the lining is for all practical purposes as efii cient as a welded or brazedor soldered union.

It will be obvious that, if'desired, the expander might. be made to travel longitudi nal'ly as well asto rotate and that the device might be made to rotate while the expander is eld stationary and that various other modifications in the construction of the apparatus might be made to suitdiflerent conditions of use withoutdeparting from the spirit of the invention. r

I claim as my invention 1. A machine for linin tubes with expansible tubes comprising a older for the tube and its lining, an ex ander adapted to act'in ternally upon the mm from end to end,- means to rotate one of said parts with respect to the other and 'means to traverse one of said parts longitudinally with respect to the other simultaneously with the act1on of the expander upon the lining. f
